CM Storm Spawn Gaming Mouse

The Spawn gaming mouse is lightweight, ergonomically designed and built for professional gamers. Engineered to execute precise in-game tactics, Spawn comes loaded with a high-performance 3500 DPI LED sensor that includes on-the-fly adjustment, an ultra-step wheel decoder for extremely accurate scrolling, and Japanese-made Omron micro-switches that are meant to endure up to 5 million clicks. The included 32KB onboard memory keeps all your settings saved even when you’re taking your game on-the-go. Spawn’s eye-catching crimson red finish compliments any high end system build and will keep you at the top of your game.

The Spawn utilizes the latest high performance optical engine, ensuring stability and reliability. Based on an anti-drift architecture, it delivers stable and precise tracking in mouse lift and drop scenarios. Angle snapping can be enabled (or disabled) for exact swift crosshair movements for incredible accuracy and enabling amazing skill-shots.
The Sentinel-X microprocessor safeguards your mouse settings by storing button assignments, advances customizable macros, and allows gamers to play and play into other systems without having to configure it all over again.
Omron’s exclusive ultra-tactile micro switches create unsurpassed tactile feedback and speed. Guaranteed 5 million clicks from these high grade switches means that the Spawn will provide an extended life-span even for the most hardcore gamers.
Conveniently placed under the scroll wheel, you can swap between DPI resolutions (800, 1800, 3500) for maximum control.
A special sweat-proof rubber compound on both sides of the Spawn keeps your hand secured. Even in heated long matches and during quick life and drop moves, you retain full control and grip.

1 out of 5 eggsGood mouse, terrible support.

Pros: This is a great mouse.

Cons: 1. The software freezes when you have Chrome browser on at the same time. I cannot believe software programmers think this is OK.
2. The mouse tracks even when off the ground by maybe quarter of an inch. New firmware apparently fixed the problem, but some people including myself noticed that the mouse then stops every 3 seconds, which made it completely unusable. So I just backtracked the firmware, and now it's ok, but it still has the original problem of tracking when off the ground.
3. My mouse in particular had its wheel scroll break after a month. I tried to RMA, and at first they asked me to pay return shipping. (What?!) I contacted CS, and they ended up giving me a free shipping label. The return took a week to ship and more than a week to process.

All in all, great mouse, but the company's product support is garbage.
I won't be buying any Cooler Master product since I know now that support for their product is garbage, even if the product itself is good.

4 out of 5 eggsFeels So Right

Pros: This mouse was made for my hand. I'm a MAC guy and have tried every mouse configuration. I was looking for simple, programable buttons. I can now edit video, do word processing, input spreadsheets reclined with minimal keyboard strokes.

Cons: NO support for MAC. This is crazy. Thank Goodness for USB overdrive.
$20 rebate took 2 months of persistance on my part to get CM Storm to get me what was promised.
USB cord is heavy gage. Very robust and durable, but restrains movement if any obstacles are on the desk.

Other Thoughts: I love this mouse. After the $20 rebate, very happy.

2 out of 5 eggsButton wearing out after 8 months

Pros: Solid but not overly heavy
Good feel
Plenty of buttons
Good grip
Good sensitivity
Good build quality

Cons: Side thumb buttons a bit too sensitive (too easily clicked)
Scroll wheel click button also too sensitive - easily misclicked while scrolling.
Left (main) mouse button switch wearing out after 8 months of use.

Manufacturer Response:

4 out of 5 eggsGood but not great

Pros: Sturdy buttons, very good scroll wheel that notches the way you want it to, solid construction overall, rubber grip on both sides, comfortable to use for wide hands, 3 dpi settings and high max dpi, several extra buttons on the mouse

Cons: Not a great mouse for small hands, sensor is below the center of the mouse

Other Thoughts: I liked everything about this mouse except the dealbreaker for me is definitely that the sensor is below the center of the mouse and pretty much all mouses I have ever used before have had their sensor in the middle. So when I do use this mouse, everything is always off for me. Shifting your fingers backwards would mean that the main buttons will be slightly out of comfortable reach.

3 out of 5 eggsGood, but won't last long

Pros: *Great for finger-tip/claw grip
*Nice scroll wheel

Cons: *Not many DPI options
*Not very durable

Other Thoughts: I had it for a bit over 2 years with heavy use, and it's starting to fail. It worked great while it lasted.

Manufacturer Response:

5 out of 5 eggs

Pros: This mouse replaces my old CMStorm Xornet.

I have been very happy with CMStorm mice.

Spawn feels smooth, light weight, and overall well built mouse.

Would recommend to anyone especially for gamers who are looking for a claw-style mouse or who have small hands like myself.

Cons: none

Other Thoughts: Will buy again when the time comes.

5 out of 5 eggsErgonomic Gamer's Mouse

Pros: Very ergonomic, if you are the kind of gripper that Cooler Master is targeting with this product. More on that later on. There is a comfortable spot for every finger on the hand - what makes this mouse look weird is its special rest for your fourth finger. I like holding it with my pointer on the left-click, middle on the right-click, fourth on its special ledge, and my pinky contacting the right side of the mouse. It's incredibly comfortable and once you get used to it, very easy to take for granted until you use another mouse.
Scroll wheel provides solid, but not preventative, feedback. I like how it clicks into notches, instead of being free spinning like my previous Logitech M325.
The extra buttons (MOUSE4 and MOUSE5) are very well-placed. All it takes is a casual flick of the thumb to hit either one of them.
The scanner - it has three basic settings, with the "DPI on the fly" feature. I will say that it's not just made to sell. Sometimes if I want more or less sensitivity all I have to do is hit one of the quick-switch buttons.

Cons: If you're not a claw-gripper (a claw-gripper is a gamer who uses his/her fingertips or fingers to manipulate the mouse) then this mouse might not work for you. I believe palm grippers need a long mouse to exert more force on. This mouse is short and wide, and it wasn't designed for it. Not worth taking an egg off for, because it's designed for claw gripping. If you're a palm gripper, this mouse isn't meant for you. Who knows, though, maybe you can learn to use it. I have heard of some people who did.

The "Switch DPI on the Fly" function won't always work. Some games, mostly fullscreen ones such as Civilizations 5, Mass Effect 3, and Team Fortress 2, don't appear to allow you to change DPI on the fly. It's not Cooler Master's fault, you have to at least give them credit for thinking of and semi-successfully implementing this function. But in my experience, you shouldn't rely a match on whether the quick-switch DPI function works after some thorough testing.

The quick-switch DPI buttons are slightly in the way. I can't say I know a better place to put them, but if you ever want to click the middle mouse button, make sure your middle finger doesn't press the sensitivity increase button.

Other Thoughts: I never use the 3500 DPI setting - at least, I haven't found a way to use it yet - and only sometimes its lowest setting. I find 1700 DPI a happy medium.

I know I put out some cons about the quick-switch mode - the buttons and the fact that it won't always work - but it IS a bit of a luxury to begin with and you won't die without it. In the situations it works in, it's great. In the situations it doesn't work in, be it a software limitation of the app or because your finger hit the wrong button, your reticle went a few pixels too far and you missed that headshot, well... you might rage, but you'll get over it. It's not a deal-breaker and in my opinion, if you plan around it - which is easy - then it's not worth taking off one egg.

The feel of this mouse will be love hate. I can't recommend this mouse to a palm-gripper. But for a claw-gripper like myself, this is the mouse for you! It is relatively inexpensive compared to certain mice by a certain sharp gaming company, and even compared to some of CM's other offerings (I think. Don't take my word for it.) I sort of stumbled on this mouse at random. I was using a Logitech M325, a slim wireless that was really made for mobility more than it was for gaming. I never thought I'd have cause to spend money on a mouse "designed for gamers". So for Christmas of 2013, my aunt, who had given me cash the previous year, took note of my newfound PC gaming hobby. I guess she went out at random and grabbed the first nice-looking mouse that wasn't cheap nor pricey, which happened to be this mouse. The Spawn showed me what it really is to have a gaming mouse. You have to love serendipity, huh?

1 out of 5 eggsFalsely Advertised w/Poor Software

Pros: It will be cheap useless expenditure (~$15) after MIR when I bought it.

It is a comfortable mouse and seems to move nicely upon initial use.

Cons: Mouse Software maps thumb buttons in reverse of visual layout in software (i.e. "Button 6" in the software maps to "Button 7" on the physical mouse, and vice versa).

Software also will not map some keyboard commands to mouse buttons. It will map "normal characters" (e.g. letters, spaces, and numbers), but compound keys (e.g. !@#$%^&, capital letters, etc) are a no go. Moreover, it will not pass Ctrl, Shift, or Alt despite the software saying it will pass said Left or Right version to the button in question on the mouse configuration software.

Other Thoughts: Using Ctrl & Alt on a mouse may seem like an odd setup, but it has it's uses in some games. With it marketed as a "gaming" oriented mouse with "7 Fully Programmable Buttons" it is what I expected. I have used Logitech and Microsoft gaming mice in the past, at near the same price point, and they have always been able to do this with zero difficulty. Extremely disappointed. I have been very pleased with CoolerMaster PC Cases in the past but I will steer clear of their peripherals from here on out.

And before any reps ask... I verified that I was using the most current version of the mouse software, and I updated the firmware to the most recent version as well (and I also restarted my PC to make sure that wasn't an issue either).

Manufacturer Response:

Hello Christopher,

I apologize for the trouble that you having with the software. We can look into this further as there are some macro combinations the mouse and software cannot perform. The Button swap is not normal on the mouse in the software. We can look into about providing a replacement for you or help troubleshoot further using the software provided with the mouse. Please contact us at 888-624-5099 or by livechat to see what we can help with. Please let us know.

5 out of 5 eggsPerfect Claw-Grip Mouse

Pros: I got this around Christmas 2013 to replace an aging Logitech wireless mouse. It's my first Cooler Master product, and it certainly won't be my last.

I personally use a claw grip, and this mouse is so comfortable I was completely used to it after five minutes. There's a little overhang on the right side which looks really, really weird, but I assure you it's not there for looks. It is the PERFECT, and I mean PERFECT rest for my ring finger. Before, using a rather slim mouse, I had to exert force with my ring finger and it was mildly uncomfortable. Now, though, my finger can be lazy! The rest of the mouse feels like it's molded to fit my hand, too. As a result, I'm only vaguely aware it's there.

Changing the DPI is also a big perk. For some games like Minecraft or Team Fortress 2 a high DPI works for me, but for others like SimCity I prefer a low DPI. Having those buttons on the mouse really saves me from having to open Windows settings and manually tweaking mouse sensitivity.

The extra switches are also very optimally placed. I'm referring to the two buttons on the left side. Your thumb naturally rests just beneath them, ready to flick upwards and hit either of them. They aren't in the way and they aren't out of the way - they ARE the way.

The onboard flash memory is also pretty handy. I don't need to worry about transferring the mouse from my laptop to a school computer with a broken PS/2 slot, it'll still remember exactly how I like it.

Cons: The DPI switches are sensitive to the touch. Beware of accidentally changing your DPI mid-game. However once you get used to the mouse's layout this almost never happens.

If you are a "palm-grip" gamer, this mouse probably isn't for you, either. It's probably too wide to control with the palm.

It's probably very easy to dislike the aesthetics of the mouse. I sort of did at first, but it grew on me, so I'm okay with the looks now.

Other Thoughts: I would recommend to Cooler Master to have an additional button which is a "DPI-lock". You have to be holding down that button in order to switch your DPI. I can't say where to put it, but I'm sure given the mouse's excellent design I'm sure CM can think of something.

In case you haven't read this in the pros or cons: this mouse will be love/hate for you depending on one thing, which is the method in which you hold the mouse. If you are a claw gripper, I would definitely recommend this mouse to you, because this mouse was born and bred to be claw gripped. That's the number one feature of this mouse, its ergonomic design for claw grips. On the other hand, if you're a palm gripper, I would discourage you to go for this mouse. The width might make it harder for you to grip the mouse.

All in all, I love my CM Spawn. It's comfortable, it's rugged, and it's functional. The cons I listed are just minor things which may or may not come up; they did not bother me a single bit.

4 out of 5 eggsGood Mouse, poor button placement

Pros: Comfortable grip: The mouse has a very comfortable grip, but one should know that it doesn't have a 'palm rest' if you have larger hands. The mouse seems to have been designed to be moved by just fingertips, which is great for high accuracy things anyway. The grips are very soft and keep hands from sweating very well.

Accurate sensor: Though it isn't a laser sensor, it still tracks very well on man different surfaces.

Soft Cord: The cord is soft enough that it can be bent and not affect the ability to move the mouse. A small pro, but something that other mice have fallen short with.

Cons: Poor button placement: The dpi setting button is directly behind the scroll wheel. When scrolling down quickly sometimes I change the dpi to some setting I'm not used to and I have to change it back, which ruins the flow of my work or potentially my game.

Other Thoughts: It's a good mouse. If it had either a different location for the dpi button or ability to force you to hold the dpi button to change the setting, it would be fine. As it is, I'm probably not going to stick with the mouse very long as I often scroll through longer documents.
